弹性搜索映射分析器 - 获取不到结果 [英] elasticsearch mapping analyzer - GET not getting result
问题描述
我正在尝试创建一个分析器,用一个空格代替特殊字符并将其转换为大写。然后,如果我想用小写搜索也应该工作。
I am trying to create an analyzer, which replaces special character with a whitespace and convert it into uppercase. then after, if I want to search with lowercase also it should work.
映射分析器:
soundarya@soundarya-VirtualBox:~/Downloads/elasticsearch-2.4.0/bin$ curl -XPUT 'http://localhost:9200/aida' -d '{
"settings": {
"analysis": {
"analyzer": {
"my_analyzer": {
"tokenizer": "standard",
"char_filter": [
"my_char_filter"
],
"filter": [
"uppercase"
]
}
},
"char_filter": {
"my_char_filter": {
"type": "pattern_replace",
"pattern": "(\\d+)-(?=\\d)",
"replacement": "$1 "
}
}
}
}
}
'
{"acknowledged":true}
soundarya@soundarya-VirtualBox:~/Downloads/elasticsearch-2.4.0/bin$ curl -XPOST 'http://localhost:9200/aida/_analyze?pretty' -d '{
"analyzer":"my_analyzer",
"text":"My name is Soun*arya?jwnne&yuuk"
}'
通过将特殊字符替换为空格来正确标记字词。现在,如果我从文本中搜索一个单词,它不会检索任何结果。
It is tokenizing the words properly by replacing the special character with the whitespace. Now if I search a word from the text, it is not retrieving me any result.
soundarya@soundarya-VirtualBox:~/Downloads/elasticsearch-2.4.0/bin$ curl -XGET 'http://localhost:9200/aida/_search' -d '{
"query":{
"match":{
"text":"My"
}
}
}'
我没有从上述GET查询中得到任何结果。获取结果如下:
I am not getting any result out of the above GET query. Getting result like :
soundarya@soundarya-VirtualBox:~/Downloads/elasticsearch-2.4.0/bin$ curl -XGET 'http://localhost:9200/aida/_search' -d '{
"query":{
"match":{
"text":"my"
}
}
}'
{"took":5,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}
任何人都可以帮我这个!谢谢!
Can anyone help me with this! Thank you!
推荐答案
创建索引后,似乎没有索引任何数据。调用 _analyze
将不会对任何内容进行索引,而只是向您展示如何分析发送给ES的内容。
You don't seem to have indexed any data after creating your index. The call to _analyze
will not index anything but simply show you how the content you send to ES would be analyzed.
首先,您需要通过指定使用您定义的分析器的映射来创建索引:
First, you need to create your index by specifying a mapping in which you use the analyzer you've defined:
curl -XPUT 'http://localhost:9200/aida' -d '{
"settings": {
"analysis": {
"analyzer": {
"my_analyzer": {
"tokenizer": "standard",
"char_filter": [
"my_char_filter"
],
"filter": [
"uppercase"
]
}
},
"char_filter": {
"my_char_filter": {
"type": "pattern_replace",
"pattern": "(\\d+)-(?=\\d)",
"replacement": "$1 "
}
}
}
},
"mappings": { <--- add a mapping type...
"doc": {
"properties": {
"text": { <--- ...with a field...
"type": "string",
"analyzer": "my_analyzer" <--- ...using your analyzer
}
}
}
}
}'
然后,您可以索引一个新的真实文档:
Then you can index a new real document:
curl -XPOST 'http://localhost:9200/aida/doc' -d '{
"text": "My name is Soun*arya?jwnne&yuuk"
}'
最后,您可以搜索:
curl -XGET 'http://localhost:9200/aida/_search' -d '{
"query":{
"match":{
"text":"My"
}
}
}'
